ATTACHMENT FOR WATER-PIPES.

Specification of Letters Patent.

Patented Apr. S, 1913.

Application 1ed March 11, 1912. Serial No. 682,868.

To `all whom t may concern Be it known that I, JOHN K. FINLAY, a citizenof the United States, residing at Llano, in the county of Llano andState of Texas, have invented a new and useful At tachment forTater-Pipes, of which the following is a specification.

This invention relates to an attachment for water pipes which willprevent the bursting of the pipes occasioned by the freezing of thewater which passes through the same.

`The primary object of the presentinvention is to provide means to bedisposed interiorly of the water pipe which will take up the expansionof the water as the same freezes, increasing the diameter of the pipethrough the contraction of said means.

lVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed it being understood th at changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawings, forming a part of this specification Figure 1 is alongitudinal section. Fig. 2 a section on the line 2 2 of Fig. l, andFig. 3 an end elevation of the device removed from pipe.

In the drawings: 10 designates the section of pipe which receives theflexible tubular This member may be of any suitable configuration and isformed of soft metal, the terminals of the member 11 being closed. Thehollow member 11 is spaced from the wall of the pipe by the radiallyextending arms 12 which hold the side Walls of the tubular member l1 atpoints equidistant from the walls of the pipe.

It will be noted that when the water said flexible member yielding morereadily to the pressure of the water thanqthe iron pipe 10. Thus it willbe noted`that the tubular member 11 may be compressed until the same ispractically flattened, this compression of the member increasing thearea of the pipe thereby preventing the same from bursting.

It will be noted that the member ll may be formed of various materialsand that the same may be spaced from the wall of the pipe in anysuitable manner.

The many advantages of a construction will be clearly apparent and itwill be noted that the same provides a simple and eiiicient means forincreasing the area of the pipe to prevent the bursting of the same bythe pressure created by the freezing of the water which passestherethrough. It will also be' noted that the structure is such that itmay be easily and economically manufactured and that the device may bereadily inserted within the pipe sections.

Having thus described the invention what is claimed as new is In a pipe,a hollow member located centrally therein, said member being formed ofsoft pliable metal and provided with closed thickened ends, circularrods disposed in said ends and extending at right angles to each otherfor maintaining said hollow member in spaced relation with respect tothe pipe.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
